Backstory
Rimuru Tempest is the son of Ray Tempest and Lufasu Mafaalu, both renowned Huntsmen who formed Team LMRZ. Lufasu, the leader, was known as the world's best Huntsman, while Ray became the world's richest person due to his inventions and contributions to Atlas, including air buses and the Cross Continental Transmit System that he gift to four nations.
Rimuru mother, Lufasu, and Ruby Rose's mother, Summer Rose, were close friends from school and their time at the Huntsman Academy. Their friendship endured even after graduation, leading to their children, Rimuru and Ruby, growing up as inseparable childhood friends. Ruby's older sister, Yang, often joined their adventures, creating a trio that was nearly unstoppable. They spent countless days playing, eating, sleeping, and even bathing together, forming bonds that would last a lifetime. Both Rimuru and Ruby shared the same birthday-October 31st-leading many to mistakenly believe they were twins sister.Since Rimuru look like a girl many who don't know about it call him little girl. Some time there mother dress them in cute girly cloth which Rimuru hate it. 
Meeting Qrow:
At the age of five, Rimuru and Ruby met Ruby's uncle, Qrow Branwen, for the first time. They were immediately fascinated by Qrow's unique hybrid weapon, which combined a large blade, shotguns, and a scythe. Inspired by its design, both Rimuru and Ruby decided they wanted to craft similar weapons. Ruby's mother, Summer, supported their ambition and promised to train them both in wielding scythes. However, Rimuru mother, Lufasu, was less enthusiastic, as she had always wanted Lucifer to follow in her footsteps as a sword master.
To make his mother happy, Rimuru decided to craft a secondary weapon-a hybrid of a sword and gun-while still keeping his promise to Ruby. This made Lufasu proud, and she began training Rimuru intensively, helping him become a master of all weapons, especially swords.
Ozpin's Request and the Grimm Attack:
When Rimuru was six years old, he and his family were on a peaceful trip to Atlas, enjoying quality time together. However, that tranquility was shattered when they received an urgent call from Professor Ozpin. He informed Ray and Lufasu that a nearby village was under attack by a massive Grimm army, and there weren't enough Huntsmen available to defend it. Aware of their unparalleled skills, Ozpin specifically requested their assistance, knowing they were among the best Huntsmen in the world. Despite the nature of their trip, Ray and Lufasu felt a deep sense of duty and answered the call to protect the innocent.
Before they departed for battle, Lufasu and Ray entrusted an Atlas female officer with taking Rimuru back to safety in Atlas, where their home was located, and their butler, Sebas, could look after him. Rimuru, filled with a mix of fear and determination, protested vehemently, wanting nothing more than to fight alongside his parents. However, the officer gently but firmly took him away, urging him to heed his parents' wishes. Torn between loyalty to his family and the instinct to protect them, Rimuru reluctantly complied, watching helplessly as his parents set off into the chaos.
The battle was fierce and relentless. Ray and Lufasu fought valiantly against the initial wave of Grimm, showcasing their unmatched combat skills. However, after hours of intense fighting, a larger and more powerful force of Grimm surged forward, overwhelming the two Huntsmen. Despite their best efforts, both were eventually fatally injured, sacrificing themselves in a final stand for the villagers before reinforcements could arrive.
Meanwhile, Rimuru, who had been taken away to safety, felt helpless as he sensed the chaos around him. His Semblance had awakened, but he was exhausted from the emotional turmoil and the strain of the situation, leading him to fall into a deep coma. When he finally awoke a week later, disoriented and grieving, he discovered a letter left for him.
The letter, written by Professor Ozpin, contained the heartbreaking news of his parents' deaths. Overwhelmed with sorrow, Rimuru broke down in tears, feeling an immense weight of loss and despair. He closed himself off from the world, retreating to his room, unable to face anyone or process the reality of his parents' sacrifice.
Professor Ozpin, upon learning of Ray and Lufasu's demise, was deeply saddened. He knew he had a duty to inform Rimuru of the tragedy, but he was unable to meet him in person, as Sebas had informed him that Rimuru was still in a coma. Instead, he left a carefully worded letter for the grieving boy, hoping to convey both the heroism of his parents and the support he would have in the difficult times ahead.
Rimuru previous Life:
Mc stood at the bus stop, gazing absentmindedly at the sunset, his mind swirling with thoughts of his favorite anime, RWBY. The series had captivated him with its intricate storytelling, compelling characters, and thrilling battles. He often imagined what it would be like to step into that world, to wield incredible powers, and to change the course of events that led to so much heartache.
As he pondered, a sudden jolt interrupted his thoughts. It felt like a push-sharp and unanticipated. Before he could react, he was knocked off balance and struck by an oncoming bus. Time slowed as he braced for impact, thoughts racing through his mind. This is it; I'm going to die.
In that moment, everything went dark.
When consciousness returned, Mc found himself standing in a vast, ethereal expanse. A figure bathed in light approached him, radiating an aura of divine power. "Sorry but, You have die because of my mistake," the figure said, its voice echoing with a resonance that transcended understanding. "So I offer you a choice: you may reincarnate in another world or reborn again as human but lose you memory."
His heart raced with excitement and fear. "Can I choose which world?" he asked, remembering the countless hours spent watching RWBY. "I want to go to Remnant."
The god nodded, a knowing smile crossing its features. "Very well. But tell me, what powers do you desire to navigate this new life?"
Mc took a deep breath, heart pounding. He envisioned the abilities he'd always dreamed of having, the powers that would allow him to not only survive but thrive in the dangerous world of Remnant.
"I want the following powers," he declared confidently:
1. Aetherial Insight: It's power is " Thought Acceleration, Analytical Appraisal, Parallel Calculation, Synthesize/Separate, Alteration, All of Creation. "it help rimuru learn everything fast like in  weapon , elements, magic etc. 
2. Gate of Babylon: "The ability to summon weapons like Gilgamesh, capable of wielding immense power."
3. Summoning: "The power to summon allies and shadow creatures  to aid me in battle."(shadow army from solo leveling) 
4. Creation: "The ability to create anything I need, except living beings."
5. Full mastery of Silver-Eyed Warrior powers: "I want to be stronger than any Silver-Eyed Warrior before me."
The god considered his requests, nodding in approval. "These powers are granted, but they will only manifest once you awaken your semblance. You will also receive a system similar to that from Solo Leveling, aiding you in your journey. However, your body must be able to withstand this power. Training will be necessary, and you will lose your memories temporarily until the system activates. But fear not; they will return to you in time."
Mc felt a wave of anticipation wash over him. This was the opportunity he had always dreamed of, the chance to change the fate of his beloved characters in RWBY. With a determined heart, he accepted the god's offer.
